Fig. 3 illustrates the method 32 that is used for determining the association status between first and second electronic installations 12,18 according to the embodiment of the invention.In embodiments of the present invention, first and second electronic installations 12,18 comprise that one or more processor (not shown) are used for the step of implementation method 32.Can expect, first electronic installation 12 can be central hub (central hub) device, peripheral unit such as second electronic device 18 is related to communicate betwixt with this central hub device, perhaps separates the communication of being set up to stop therebetween with armature assembly (central hub device) in this.In embodiments of the present invention, middle armature assembly 12 is a gateway, and it is configured to communicate with the related with it peripheral unit 18 such as patient-monitoring transducer or health object wearing device.Correspondingly, gateway 12 is configured to wirelessly collect the patient health parameter of being gathered by patient-monitoring transducer 18, is used for health care patient's treatment and monitoring.
With reference to figure 3, method 32 starts from step 34, its detection or sensing gateway 12 and peripheral unit 18 closely adjacent.Closely adjacent is to determine according to following adjacent states, has mutual reciprocation between the contiguous sensing system 16,22 of this adjacent states indicating device 12,18, as shown in Figure 1.According to the embodiment of the invention, after the closely adjacent detection of step 34,, in each device 12,18, enable and be provided with or activate timer in step 36.The timer of each device in 12,18 haply with proximity detection synchronously and set predetermined amount of time, this defines a time scope, is used for determining that the method 32 of association status should carry out in this time range.In addition, and will be hereinafter more fully describe, timer helps identification to be sought association status and from the device 12,18 of its received communication.Even but the activation of timer also makes after gateway 12 and peripheral unit 18 are no longer contiguous and to need only communication system 14,20 respectively within communication zone 26,24 by the still remaining step of processing method 32 in step 36.
Activate after 36 at timer, in step 40, gateway disassociation frame or netkey are sent to peripheral unit 18 from gateway 12.Association status communication between the transmission starting apparatus 12,18 of the gateway disassociation frame of step 40.In one embodiment, the gateway disassociation frame uses acquiescence radio channel and default address to transmit, and wherein said default value is known for all devices related or that separate.Use feasible successfully association of default parameters or separation, and exchange wireless discovery message before noting be used in device 12 and 18 vicinities.The gateway disassociation frame comprises communications slot (communication slot) information of relevant wireless network and the information of the timer of relevant gateway 12.For example, gateway timer information can comprise the current state or the counting of gateway timer.In step 42, peripheral unit 18 is explained the gateway disassociation frames and with the timer comparison of gateway timer information and peripheral unit 18.If the timer of peripheral unit 18 at the fixed time in section or the scope corresponding to the timer of gateway 12, then to know the gateway disassociation frame that is received as from correct gateway 12 to peripheral unit 18.Peripheral unit 18 is the data in step 42 is explained the gateway disassociation frame also, and determine current association status or the network state of peripheral unit 18 to gateway 12 in step 44.
Current association status is based on association status data in the internal storage that is stored in peripheral unit 18, between gateway 12 and the peripheral unit 18.If these data are zero, equal predetermined value, perhaps in the scope of predetermined value, then indicate peripheral unit 18 related with gateway 12; Otherwise this data indication peripheral unit 18 is related with gateway 12.
If current association status is related with gateway 12 at 46 indication peripheral units 18, then in step 48, whether peripheral unit 18 these disassociation frames of inspection are opened with definite communications slot and be can be used for peripheral unit 18 is associated with gateway 12.According to the embodiment of the invention, communications slot as known in the art, is meant the time interval that limits in the time division multiple access network.In addition, as known in the art, communications slot also refers to, for the desired service quality between the parts that guarantee wireless network, adopts the maximum node number that allows in the network of Carrier Sense Multiple Access or other access to netwoks schemes.In addition, in embodiments of the present invention, disassociation frame comprises connective marker, and described connective marker is corresponding to the corresponding communication groove and to identify this respective communication groove be available or unavailable.For example, in the network with 16 communications slots, 16 connective markers can be corresponding to the information (AT0 and AT1) of two bytes in the disassociation frame.The AT0 value remains 14 groove free time for but two grooves of 0x00 indicating head are unavailable for 0xC0 and AT1 value.In addition, for each connective marker, disassociation frame comprises ID part (that is, SN0, SN1, SN2...), with ID number of expression gateway appointment.In one embodiment of the invention, corresponding with unavailable communications slot and partly comprise nonzero value with the corresponding ID of the first available communication groove.If there is not open communication groove 50 to be used for peripheral unit 18 is associated with gateway 12, for example, when the value of AT0 and AT1 is 0xFF, it is full indication that peripheral unit 18 provides network in step 52, make attempting that peripheral unit 18 is associated with the operating personnel of gateway 12 or technical staff, to be apprised of network full, and this also indicates peripheral unit 18 not related with gateway 12.According to the embodiment of the invention, for the purpose of informing, peripheral unit 18 can comprise noise and form device, LED or other sighting devices, perhaps haptic device, the vibration unit of for example informing operating personnel by sound, light or haptic methods.In another embodiment, this informs it can is implicit expression, because after association is set up, successful association will cause in the outside still communication within communication range of nearby sphere.Be used to inform that other apparatus and method of operating personnel also are considered as dropping within the scope of the embodiment of the invention.After 52 inform that network is full, the peripheral unit timer be eliminated or forbid 53 and method 32 finish 54.
Refer again to step 48, if communications slot open 56 and can be used for peripheral unit 18 is associated with gateway 12, peripheral unit 18 transmits the related information bag in step 58 and replys gateway 12, and this related information bag is replied the number that comprises the local sign of its transducer (ID) number, its timer information and available communications slot.If the timer of peripheral unit 18 is section or the interior timer corresponding to gateway 12 of scope at the fixed time, then upgrade these disassociation frames and the disassociation frame that upgrades is sent to peripheral unit 18 at step 60 gateway 12.In one embodiment of the invention, gateway 12 upgrades disassociation frame by following operation: the transducer of the transducer local I being write disassociation frame for D number is confirmed (SNACK) part, upgrade AT0 or AT1 and become unavailable to indicate available communication groove by peripheral unit 18 identifications, be identified for non-zero gateway assigned I D by the groove of peripheral unit 18 identifications, write on the operation address (OPADR) of the message that exchanges during the operator scheme, write on the operating walk way (OPCHL) that uses during the operator scheme, and the timer information of new gateway 12 more.This operating walk way can relate to special carrier frequency, frequency pattern (pattern), be used for the code of code division multiple access or be used for sharing other mechanism of wireless medium.In one embodiment, operating walk way and operation address are unique for particular gateway device 12, and offer all peripheral units 18 in the gateway disassociation frame.
Peripheral unit receives and explains the disassociation frame that upgrades in step 62.If the timer of gateway 12 in preset range corresponding to the timer of peripheral unit 18, the data of peripheral unit 18 in the disassociation frame of this renewal of step 62 checking then.In one embodiment, peripheral unit 18 its transducer local idents of checking are stored in the SNACK.The timer of peripheral unit 18 is cleared or forbids in step 63, and peripheral unit 18 is informed the related success of operating personnel and gateway 12 in step 64.In addition, can imagine that peripheral unit 18 can inform that whether operating personnel will oneself be associated with network and add network in the in the end remaining open network groove of peripheral unit 18.Therefore, except informing that operating personnel are successfully associated, operating personnel can be apprised of the present fullcharging of this network, and indication no longer includes peripheral unit and can add the current network setting again to.Peripheral unit 18 also is stored in the operation address (OPADR) and the operating walk way (OPCHL) of its gateway assigned I D, gateway 12 in its internal storage in step 66.Process control finishes 54 subsequently.It will be apparent to those skilled in the art that step 63-66 can resequence according to embodiments of the invention.At this moment, device 12,18 is associated, and is converted to the operator scheme (not shown) of the further exchange that data and information wherein may take place.
Refer again to step 44, if current association status is associated with gateway 12 at 68 indication peripheral units 18, then peripheral unit 18 checks that in step 70 disassociation frame is to determine whether gateway 12 is associated with peripheral unit 18.In embodiments of the present invention, peripheral unit 18 obtains its gateway assigned I of being stored in its internal storage D number, and with the assigned I D comparison in the ID part of its assigned I D number and disassociation frame.If be stored in (for example among the SN2) in the peripheral unit 18 assigned I D number coupling 72 disassociation frame assigned I D number, then peripheral unit 18 transmits its transducer local I D number, its timer information and by the number of gateway 12 to the communications slot of its appointment in step 74.If the timer of peripheral unit 18 is section or the interior timer corresponding to gateway 12 of scope at the fixed time, then gateway 12 receives, upgrades and transmits the disassociation frame of this renewal to peripheral unit 18 in step 76.In one embodiment, this communications slot of gateway 12 checking number and peripheral unit 18 are related and the transducer local I write SNACK D number.Gateway 12 also upgrades this disassociation frame by following operation: determines assigned I D number and next idle groove of related with it ID part, upgrades connective marker AT0 and AT1 as required, and the timer information of new gateway 12 more.
In step 78, if the timer of peripheral unit 18 at the fixed time in section or the scope corresponding to the timer of gateway 12, then the gateway disassociation frame of this renewal is explained and verified to peripheral unit 18.For example, peripheral unit 18 its transducer local idents of checking are stored in the SNACK.After this checking, peripheral unit 18 informs that in step 80 this peripheral unit 18 of operating personnel separates with gateway 12.Peripheral unit 18 is also removed any gateway assigned I D that is stored in its internal storage in step 82.The timer of peripheral unit 18 is cleared or forbids in step 83, and peripheral unit 18 enters standby mode in step 84, and peripheral unit 18 does not transmit by wireless communication system 20 during this standby mode and receives message, detects vicinity once more until it.Process control finishes in step 85 subsequently.
Refer again to step 70, if be stored in assigned I D number 86 disassociation frames that do not match in the peripheral unit 18 assigned I D number, then peripheral unit 18 is open to have determined whether communications slot at step 88 decoding connective marker.If there is the communications slot can be with 90, process control proceeds to above-mentioned step 80, informs that this peripheral unit 18 of operating personnel separates with gateway 12, and removes any gateway assigned I D that is stored in the internal storage.If communications slot is unavailable 92, peripheral unit 18 is informed this network fullcharging of operating personnel in step 94, removes any gateway assigned I D that is stored in the internal storage in step 82, and at the timer of step 83 forbidding peripheral unit 18.Process control finishes in step 84 subsequently.It will be apparent to those skilled in the art that step 80,82 and 83 order and step 94,82 and 83 order can resequence according to embodiments of the invention.
Correspondingly, described with reference to figure 3 as mentioned, if current association status indicates this peripheral unit 18 not related with gateway 12, then peripheral unit 18 is attempted making self related with gateway 12.If network opening, promptly, exist and to be used for the open communication groove of communicating by letter with gateway 12, then peripheral unit 18 will self be associated with gateway 12 and become the part of all device cordless communication networks of 18 of communicating by letter with gateway 12, and wherein this association comprises peripheral unit 18 self is assigned to this open communication groove.If the network fullcharging promptly, does not exist to be used for the open communication groove of communicating by letter with gateway 12, then peripheral unit 18 keeps separating with gateway 12 and does not form the part that all of communicate by letter with gateway 12 are installed 18 network.
On the other hand, if current association status indication peripheral unit 18 is related with gateway 12, then peripheral unit 18 is removed self and self is separated with gateway 12 from being installed 18 network with all of gateway 12 communications.If peripheral unit 18 determines that from disassociation frame gateway 12 is associated peripheral unit 18 with it and in wireless network, then 12 communications separate peripheral unit 18 with collaborative peripheral unit 18 with gateway 12 with gateway.If peripheral unit 18 determines that from disassociation frame gateway 12 is not related with it and not in wireless network, then peripheral unit 18 separates self with gateway 12, and does not communicate by letter with this gateway 12 with peripheral unit 18.
Although the embodiment that above describes in Fig. 3 uses timer, make at device 12,18 Method Of Accomplishment 32 when moving on to outside the adjacent domain 30,28 respectively, but according to another embodiment of the present invention, method 32 can be performed and be not provided with or starting device 12,18 in timer.Therefore, can imagine that if timer is not enabled, at least for the interrelated of device 12,18 or separation, finishing of method 32 can only be finished under device 12,18 situations about remaining on respectively in the adjacent domain 30,28.That is to say that if install 12,18 vicinities, then method 32 can be finished.Stop vicinity if installed 12,18 before method 32 is finished, then method 32 can't be finished.In addition, if in method 32, do not use timer, then do not carry out timer activation, transmission, comparison and deexcitation.
With reference now to Fig. 4,, flow chart illustrates the timer interrupt routine 138 according to the embodiment of the invention.When using timer in the method 32 at Fig. 3, the transducer timer stopped before the step 53,63 and 83 of Fig. 3 is cleared, and this will cause timer interrupt routine 138 to be carried out in peripheral unit 18.In step 140, terminating in of the timer of peripheral unit 18 begins separating step in the peripheral unit 18.In step 142, operating personnel be apprised of that timer has stopped and also can be apprised of peripheral unit 18 with or will separate with gateway 12.Peripheral unit 18 is removed any gateway ID that is stored in its internal storage in step 144 subsequently, therefore peripheral unit 18 is separated with gateway 12.Process control finishes in step 146 subsequently.It will be apparent to those skilled in the art that step 142-144 can resequence according to embodiments of the invention.
Fig. 5 illustrates the flow chart according to the communication failure program 148 of the embodiment of the invention.When the peripheral unit 18 of association detected the gateway related with it 12 communication failure is arranged, communication failure program 148 was performed.Peripheral unit 18 can be carried out this communication failure program 148 after predetermined no call duration time or after predetermined communication failure number of times.In step 150, peripheral unit 18 detects the communication failure with gateway 12.In step 152, peripheral unit 18 inform operating personnel its with or will separate with gateway 12.Operating personnel also can be apprised of communication failure and take place.Peripheral unit 18 is removed any gateway ID that is stored in its internal storage in step 154 subsequently, therefore peripheral unit 18 is separated with gateway 12.Process control finishes in step 156 subsequently.It will be apparent to those skilled in the art that step 152-154 can resequence according to embodiments of the invention.
Fig. 6 illustrates according to the embodiment of the invention and is used for verifying and the related middle armature assembly 120 of indicating each device 120-124 of wireless network and the schematic block diagram of peripheral unit 122,124.In switch on the armature assembly 120 or button 126 activate causing wireless signal 128 to send to peripheral unit 122,124 and to be received by operating personnel by peripheral unit 122,124, they are related with middle armature assembly 120 to signal operating personnel.In one embodiment, wireless signal 128 is broadcast to all peripheral units 122,124 immediately.In another embodiment, each peripheral unit 122 receives wireless signal 128 during the communication time slot of itself and middle armature assembly 120.Each peripheral unit 122,124 comprises indicating device 130, is used for indicating to operating personnel the association status of itself and armature assembly.Indicating device 130 can be that noise forms device, light-emitting diode (LED), LCD (LCD) or other sighting devices, perhaps the haptic device of vibration unit for example.Related peripheral unit 122 receives wireless signal 128 and activates indicating device 130, to signal itself and middle armature assembly 120 related 132.Yet when the button 126 on the central armature assembly 120 was activated, Guan Lian peripheral unit 124 can not indicated the association status with middle armature assembly 120.
Still with reference to figure 6, in alternative, it is movable that indicating device 130 becomes for the peripheral unit 122 of association after activating, and maintenance activity or lasting this related duration of semi-active state.For example, indicating device 130 can be LED, and it goes out related to indicate by glittering and sudden strain of a muscle under semi-active state, thereby reduces the battery power consumption.
